583 * The following subinterface syntax is supported. The first two are for
584 * backwards compatability:
587 * - a subinterface with the name <intf-name>.<id>. The subinterface
588 * is a single dot1q vlan with vlan id <id> and exact-match semantics.
590 * <intf-name> <min_id>-<max_id>
591 * - a set of the above subinterfaces, repeating for each id
592 * in the range <min_id> to <max_id>
594 * In the following, exact-match semantics (i.e. the number of vlan tags on the
595 * packet must match the number of tags in the configuration) are used only if
596 * the keyword exact-match is present. Non-exact match is the default.
598 * <intf-name> <id> dot1q <outer_id> [exact-match]
599 * - a subinterface with the name <intf-name>.<id>. The subinterface
600 * is a single dot1q vlan with vlan id <outer_id>.
602 * <intf-name> <id> dot1q any [exact-match]
603 * - a subinterface with the name <intf-name>.<id>. The subinterface
604 * is a single dot1q vlan with any vlan id.
606 * <intf-name> <id> dot1q <outer_id> inner-dot1q <inner_id> [exact-match]
607 * - a subinterface with the name <intf-name>.<id>. The subinterface
608 * is a double dot1q vlan with outer vlan id <outer_id> and inner vlan id
611 * <intf-name> <id> dot1q <outer_id> inner-dot1q any [exact-match]
612 * - a subinterface with the name <intf-name>.<id>. The subinterface
613 * is a double dot1q vlan with outer vlan id <id> and any inner vlan id.
615 * <intf-name> <id> dot1q any inner-dot1q any [exact-match]
617 * - a subinterface with the name <intf-name>.<id>. The subinterface
618 * is a double dot1q vlan with any outer vlan id and any inner vlan id.
620 * For each of the above CLI, there is a duplicate that uses the keyword
621 * "dot1ad" in place of the first "dot1q". These interfaces use ethertype
622 * 0x88ad in place of 0x8100 for the outer ethertype. Note that for double-
623 * tagged packets the inner ethertype is always 0x8100. Also note that
624 * the dot1q and dot1ad naming spaces are independent, so it is legal to
625 * have both "Gig3/0/0.1 dot1q 100" and "Gig3/0/0.2 dot1ad 100". For example:
627 * <intf-name> <id> dot1ad <outer_id> inner-dot1q <inner_id> [exact-match]
628 * - a subinterface with the name <intf-name>.<id>. The subinterface
629 * is a double dot1ad vlan with outer vlan id <outer_id> and inner vlan
632 * <intf-name> <id> untagged
633 * - a subinterface with the name <intf-name>.<id>. The subinterface
634 * has no vlan tags. Only one can be specified per interface.
636 * <intf-name> <id> default
637 * - a subinterface with the name <intf-name>.<id>. This is associated
638 * with a packet that did not match any other configured subinterface
639 * on this interface. Only one can be specified per interface.

820 * This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
821 * The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
822 * (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
823 * assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
824 * but this is not recommended.
826 * This command has several variations:
827 * - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
828 * process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
830 * - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
831 * '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
832 * match any other subinterfaces should be sent to this subinterface.
834 * - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
835 * '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
836 * to this subinterface.
838 * - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
839 * subinterfaces to handle a range of VLAN IDs.
841 * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
842 * Use this command to specify the outer VLAN ID, to either be explicit or to make the
843 * VLAN ID different from the '<em>subId</em>'.
845 * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
846 * <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
849 * When '<em>dot1q</em>' or '<em>dot1ad</em>' is explicitly entered, subinterfaces
850 * can be configured as either exact-match or non-exact match. Non-exact match is the CLI
851 * default. If '<em>exact-match</em>' is specified, packets must have the same number of
852 * VLAN tags as the configuration. For non-exact-match, packets must at least that number
853 * of tags. L3 (routed) interfaces must be configured as exact-match. L2 interfaces are
854 * typically configured as non-exact-match. If '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
855 * entered, then the default behavior is exact-match.
857 * Use the '<em>show interface</em>' command to display all subinterfaces.
861 * Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
862 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
864 * The previous example is shorthand and is equivalent to:
865 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
868 * Example of how to create a subinterface number that is different from the VLAN ID:
869 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
872 * Examples of how to create q-in-q and q-in-any subinterfaces:
873 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
874 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
876 * Examples of how to create dot1ad interfaces:
877 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
878 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
881 * Examples of '<em>exact-match</em>' versus non-exact match. A packet with
882 * outer VLAN 100 and inner VLAN 200 would match this interface, because the default
883 * is non-exact match:
884 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
886 * However, the same packet would NOT match this interface because '<em>exact-match</em>'
887 * is specified and only one VLAN is configured, but packet contains two VLANs:
888 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match}
891 * Example of how to created a subinterface to process untagged packets:
892 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 untagged}
894 * Example of how to created a subinterface to process any packet with a VLAN ID that
895 * does not match any other subinterface:
896 * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 7 default}
898 * When subinterfaces are created, they are in the down state. Example of how to
899 * enable a newly created subinterface:
900 * @cliexcmd{set interface GigabitEthernet2/0/0.7 up}

2339 * This command is used to start or stop a packet capture, or show
2340 * the status of packet capture.
2342 * This command has the following optional parameters:
2345 * - <b>rx</b> - Capture received packets
2347 * - <b>tx</b> - Capture transmitted packets
2349 * - <b>drop</b> - Capture dropped packets
2351 * - <b>off</b> - Stop capturing packets, write results to the specified file
2353 * - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
2354 * of packets have been received, buffer is flushed to file. Once another
2355 * '<em>nn</em>' number of packets have been received, buffer is flushed
2356 * to file, overwriting previous write. If not entered, value defaults
2357 * to 100. Can only be updated if packet capture is off.
2359 * - <b>max-bytes-per-pkt <nnnn></b> - Maximum number of bytes to capture
2360 * for each packet. Must be >= 32, <= 9000.
2362 * - <b>preallocate-data</b> - Preallocate the data buffer, to avoid
2363 * vector expansion delays during pcap capture
2365 * - <b>free-data</b> - Free the data buffer. Ordinarily it's a feature
2366 * to retain the data buffer so this option is seldom used.
2368 * - <b>intfc <interface-name>|any</b> - Used to specify a given interface,
2369 * or use '<em>any</em>' to run packet capture on all interfaces.
2370 * '<em>any</em>' is the default if not provided. Settings from a previous
2371 * packet capture are preserved, so '<em>any</em>' can be used to reset
2372 * the interface setting.
2374 * - <b>filter</b> - Use the pcap rx / tx / drop trace filter, which
2375 * must be configured. Use <b>classify filter pcap...</b> to configure the
2376 * filter. The filter will only be executed if the per-interface or
2377 * any-interface tests fail.
2379 * - <b>error <node>.<error></b> - filter packets based on a specific error.
2380 * For example: error {ip4-udp-lookup}.{No listener for dst port}
2382 * - <b>file <name></b> - Used to specify the output filename. The file will
2383 * be placed in the '<em>/tmp</em>' directory, so only the filename is
2384 * supported. Directory should not be entered. If file already exists, file
2385 * will be overwritten. If no filename is provided, the file will be
2386 * named "/tmp/rx.pcap", "/tmp/tx.pcap", "/tmp/rxandtx.pcap", etc.
2387 * Can only be updated if packet capture is off.
2389 * - <b>status</b> - Displays the current status and configured attributes
2390 * associated with a packet capture. If packet capture is in progress,
2391 * '<em>status</em>' also will return the number of packets currently in
2392 * the local buffer. All additional attributes entered on command line
2393 * with '<em>status</em>' will be ignored and not applied.
2396 * Example of how to display the status of a tx packet capture when off:
2397 * @cliexstart{pcap trace status}
2398 * max is 100, for any interface to file /tmp/vpe.pcap
2399 * pcap tx capture is off...
2401 * Example of how to start a tx packet capture:
2402 * @cliexstart{pcap trace tx max 35 intfc GigabitEthernet0/8/0 file
2405 * Example of how to display the status of a tx packet capture in progress:
2406 * @cliexstart{pcap trace status}
2407 * max is 35, for interface GigabitEthernet0/8/0 to file /tmp/vppTest.pcap
2408 * pcap tx capture is on: 20 of 35 pkts...
2410 * Example of how to stop a tx packet capture:
2411 * @cliexstart{pcap trace off}
2412 * captured 21 pkts...
2413 * saved to /tmp/vppTest.pcap...
